Description

FIELD OF THE INVENTION

The present invention relates to a curtain assembly, and more particularly, to a curtain assembly having tube units connected thereon and control ropes are protected within the tubes.

BACKGROUND OF THE INVENTION

A conventional curtain assembly generally includes a top box and the curtain is connected to the lower end of the top box. The curtain includes multiple sections separated by transverse passages in which rods are inserted. A plurality of rings are fixed to the curtain where the passages are located and control ropes have top ends connected with the scrolling mechanism in the top box and the lower ends of the control ropes extend through the rings and finally fixed to the rings located at the lower end of the curtain. When the user operates the control ropes to lift the curtain, the control ropes lift the fixed rings upward and the curtain is collected sections by sections which are overlapped to each other. However, the control ropes do not have any protection means and are exposed to the children so that the control ropes may trap the children who are playing the control ropes. Besides, the control ropes pass through the rings and are fixed only to the rings located at the lower end of the curtain, so that the control ropes tend to be worn out with the rings.

The present invention intends to provide a tube unit connected to the curtain assembly and the control ropes are located within the tubes of the tube unit, so that the control ropes are protected.

SUMMARY OF THE INVENTION

The present invention relates to a curtain assembly which comprises a top box and a curtain is connected to the top box. Multiple movable rings connected to the curtain and located in rows. Multiple fixed rings are fixed to a lower end of the curtain and located in align with the movable rings. A plurality of tube units each have a fixed tube and multiple movable tubes. The fixed tube includes a first passage defined therethrough, a first flange and a first insertion end are located at two ends of the fixed tube. Each of the movable tubes has a second passage defined therethrough. A second flange and a second insertion end are located at two ends of each of the movable tubes. The fixed tubes extend through the fixed rings and the first flanges are supported on the fixed rings. The first insertion end of each of the fixed tubes is fixed to the fixed ring corresponding thereto. The movable tubes extend through the movable rings and the second flanges are supported on the movable rings corresponding thereto. Multiple control ropes extend from the top box and extend through the movable tubes and the fixed tubes.

The primary object of the present invention is to provide a curtain assembly wherein the control ropes are protected within the movable and fixed tubes.

The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 1 to 7, the curtain assembly 20 of the present invention comprises a top box 21 in which a scrolling mechanism is received, and a curtain 22 is connected to the top box 21. The curtain 22 includes multiple sections separated by transverse passages in which rods are inserted. Multiple movable rings 220 are connected to the curtain 22 and located in rows. Multiple fixed rings 221 are fixed to a lower end of the curtain 22 and located in align with the movable rings 220. The movable rings 220 and the fixed rings 221 are located at the transverse passages.

A plurality of tube units 10 are connected to the curtain 22 and each tube unit 10 has a fixed tube 11 and multiple movable tubes 12. The fixed tube 11 includes a first passage 110 defined therethrough and a flange 111 extends radially from a first end thereof. A first insertion end 112 is located at a second end of the fixed tube 11. Each of the movable tubes 12 has a second passage 120 defined therethrough and a second flange 121 extends radially from a first end thereof. A second insertion end 122 is located at a second end of each of the movable tubes 12. The fixed tubes 11 extend through the fixed rings 221 and the first flanges 111 are supported on the fixed rings 221. The first insertion end 112 of each of the fixed tubes 11 is fixed to the fixed ring 221 corresponding thereto. The movable tubes 12 extend through the movable rings 220 and the second flanges 121 are supported on the movable rings 220 corresponding thereto. The fixed tubes 11 and the movable tubes 12 can be tapered tubes or cylindrical tubes. The inner diameter of the movable rings 220 is smaller than the diameter of each of the second flanges 121 of the movable tubes 12. The inner diameter of the fixed rings 221 is smaller than the diameter of each of the first flanges 111 of the fixed tubes 11. By the specific arrangement, the first flanges 111 are supported on the fixed rings 221 and the second flanges 121 are supported on the movable rings 220.

Multiple control ropes 210 extend from the top box 21 and extend through the movable tubes 12 and the fixed tubes 11. The lower end of each control ropes 210 extends through the first insertion end 112 of the fixed tube 11 and is fixed to the lower end of the curtain 22. In other words, the control ropes 210 are protected by the fixed and movable tubes 11, 12 so that the control ropes 210 are not touched by the users and children.

When the curtain 22 is lifted by pulling the control ropes 210 as shown in FIG. 6, the movable tubes 12 are inserted into the next one in sequence by inserting the second insertion end 122 of one movable tube 12 into the second passage 120 of the next movable tube 12. The second insertion end 122 of the lowest movable tube 12 is inserted into the first passage 110 of the fixed tube 11 corresponding thereto. Therefore, the curtain 22 is collected sections by sections in sequence and the movable tubes 12 and the fixed tubes 11 are inserted into each other to guide the collection of the curtain 22. The control ropes 210 freely extend through the fixed and movable tubes 11, 12 so that they are not worn out or tangled.

The fixed and movable tubes 11, 12 ensure that the control ropes 210 are well protected from being accessed by children so that the curtain assembly is safety and reliable. The control ropes 210 are located within the fixed and movable tubes 11, 12 so that the control ropes 210 are not worn out as mentioned in the conventional example.

While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
